The invention relates to the preparation of optically readable codes.
A code is optically readable symbology, that is to say, a graphical representation of a dataset. Various formats have been proposed to codify how to produce an image that corresponds biuniquely to input data. These formats include, for example: Matrix (ISO / IEC 16022), Maxicode (ISO / IEC 16023), QR-Code (ISO / IEC 18004), among others.
